Table 5.2 Troubleshooting
If the appliance was blocked by its safety systems, it can
only automatically ignite again once you have "reset" it.
To "reset" the appliance, either:
>
Close the water tap and open it again without press-
ing the main switch, or
>
Leave the water tap open and switch the appliance
off and on again by pressing the main switch (5)
twice.
Depending on the installation conditions, the unit may
have to be "reset" several times before it ignites auto-
matically; this is particularly true when commissioning
the unit and if it has been out of operation for some
time. Please follow the instructions in Section 5.3 Start-
up.
When the fault is eliminated, the gas instantaneous
water heater starts up automatically.
If the malfunction recurs, have an engineer come to
inspect the appliance.
